Access the console on DEBUG serial port
The serial console can be accessed from two connectors. One is from the DEBUG port with the help of a TTL-to-USB serial cable (marked as DEBUG J11), another is from micro-A USB connector that gives access to the on-board serial-to-USB converter (marked as J1 USB_A).Using DEBUG on TTL-to-USB connector (DEBUG J11)
- For Microsoft Windows users: Install the driver of your USB TTL serial cable. FTDI-based ones are the most popular, have a look to this page to get the driver: http://www.ftdichip.com/Drivers/VCP.htm
- Be sure to connect a 3.3V compatible cable and identify its GND pin. Place it properly according to the silkscreen and connect the cable to the board (J11)
- Make sure the jumpers J14 and J15 are closed on the side marked as DBGU for the UART to work as Debug console.
- For Microsoft Windows users: Identify the USB connection that is established,
USB Serial Portshould appear in Device Manager. TheCOMxxnumber will be used to configure the terminal emulator.
- For Linux users: Identify the serial USB connection by monitoring the last lines of
dmesgcommand. The/dev/ttyUSBxnumber will be used to configure the terminal emulator.[605576.562740] usb 1-1.1.2: new full-speed USB device number 17 using ehci-pci [605576.660920] usb 1-1.1.2: New USB device found, idVendor=0403, idProduct=6001 [605576.660933] usb 1-1.1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [605576.660939] usb 1-1.1.2: Product: TTL232R-3V3 [605576.660944] usb 1-1.1.2: Manufacturer: FTDI [605576.660958] usb 1-1.1.2: SerialNumber: FTGNVZ04 [605576.663092] ftdi_sio 1-1.1.2:1.0: FTDI USB Serial Device converter detected [605576.663120] usb 1-1.1.2: Detected FT232RL [605576.663122] usb 1-1.1.2: Number of endpoints 2 [605576.663124] usb 1-1.1.2: Endpoint 1 MaxPacketSize 64 [605576.663126] usb 1-1.1.2: Endpoint 2 MaxPacketSize 64 [605576.663128] usb 1-1.1.2: Setting MaxPacketSize 64 [605576.663483] usb 1-1.1.2: FTDI USB Serial Device converter now attached to ttyUSB0A /dev/ttyUSB0 node has been created.

Create a SD card with the demo
You need a 1 GB SD card (or more) and to download the image of the demo. The image is compressed to reduce the amount of data to download. This image contains:- a FAT32 partition with the AT91Bootstrap, U-Boot and the Linux Kernel (zImage and dtb).
- an EXT4 partition for the rootfs.
Multi-platform procedure
To write the compressed image on the SD card, you will have to download and install balenaEtcher. This tool, which is an Open Source software, is useful since it allows to get a compressed image as input. More information and extra help available on the balenaEtcher website.
- Insert your SD card and launch
Etcher:
- Select the demo image. They are marked as "SD Card image" in the demo table above.
Note that you can select a compressed image (like the demos available here). The tool is able to decompress files on the fly - Select the device corresponding to your SD card (Etcher proposes you the devices that are removable to avoid erasing your system disk)
- Click on the
Flash!button - On Linux, Etcher finally asks you to enter your root password because it needs access to the hardware (your SD card reader or USB to SD card converter)
- then the flashing process begins followed by a verification phase (optional)
- Once writing done, Etcher asks you if you want to burn another demo image:
- Your SD card is ready!
Flash the demo
use SAM-BA 3.8.y onwards. You can download it here: SAM-BA 3.8.1 release page.
Connect the USB to the board before launching SAM-BA
- Ensure SDCARD is not inserted
- Make sure that J4
NAND BOOTjumper is kept closed - Press SW3
nRSTreset button to boot from on-chip Boot ROM- For Microsoft Windows users: verify that the USB connection is well established
AT91 USB to Serial Convertershould appear in Device Manager. If it shows a unknown device you need to download and install the driver: AT91SAM USB CDC driver
- For Linux users: check /dev/ttyACMx by monitoring the last lines of
dmesgcommand:
- For Microsoft Windows users: verify that the USB connection is well established

Run script to flash the demo
- download the demo package for the board. They are marked as "Media type: NAND Flash " in the table above
- extract the demo package
- run your usual terminal emulator and enter the demo directory
- make sure that the
sam-baapplication is in your Operating System path so that you can reach it from your demo package directory - for Microsoft Windows users: Launch the
demo_linux_nandflash.batfile - for Linux users: Launch the
demo_linux_nandflash.shfile - this script runs SAM-BA 3 and the associated
QMLsam-ba script (demo_linux_nandflash_usb.qml) with proper parameters - when you reach the end of the flashing process (this will take a few minutes), the following line is written:
-I- === Done. ===
- connect a serial link on DBGU and open the terminal emulator program as explained just above
- power cycle the board
- monitor the system while it's booting on the LCD screen or through the serial line
Build From source code
Setup ARM Cross Compiler
- First step is to dowload the ARM GNU Toolchain:
wget -c https://developer.arm.com/-/media/Files/downloads/gnu/13.2.rel1/binrel/arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz
- Next step is to add the ARM GNU Toolchain into your system:
tar -xf arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz export CROSS_COMPILE=`pwd`/arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-ortar -xf arm-gnu-toolchain-13.2.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz export CROSS_COMPILE=arm-none-linux-gnueabihf- export PATH=$PATH:/YOUR/PATH/TO/arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-linux-gnueabihf/bin/
- !Note: If you already have an old ARM GNU Toolchain need to clean up the PATH with:
export PATH=${PATH/':/YOUR/PATH/TO/arm-gnu-toolchain-VERSION-x86_64-arm-none-linux-gnueabihf/bin/'/}
Build AT91Bootstrap from sources
This section describes how to get source code from the git repository, how to configure with the default configuration, how to customize AT91Bootstrap based on the default configuration and finally to build AT91Bootstrap to produce the binary. take the default configuration to download U-Boot from NandFlash for example.Get AT91Bootstrap Source Code
You can easily download AT91Bootstrap source code on the at91bootstrap git repository.To get the source code, you should clone the repository by doing:
$ git clone https://github.com/linux4sam/at91bootstrap.git Cloning into 'at91bootstrap'... remote: Enumerating objects: 17621, done. remote: Counting objects: 100% (3324/3324), done. remote: Compressing objects: 100% (1029/1029), done. remote: Total 17621 (delta 2465), reused 3102 (delta 2285), pack-reused 14297 Receiving objects: 100% (17621/17621), 5.65 MiB | 4.65 MiB/s, done. Resolving deltas: 100% (13459/13459), done. $ cd at91bootstrap/
Configure AT91Bootstrap
Assuming you are at the AT91Bootstrap root directory, you will find aconfigs folder which contains several default configuration files: sam9x60_curiositynf_uboot_defconfig sam9x60_curiositysd_uboot_defconfig
Tips: qspi means to read quad-SPI serial flash, sd means to read mmc card, nf means to read nand flashYou can configure AT91Bootstrap to load U-Boot binary from SD Card by doing:
$ make mrproper $ make sam9x60_curiositysd_uboot_defconfigIf the configuring process is successful, the .config file can be found at AT91Bootstrap root directory.
Customize AT91Bootstrap
If the default configuration doesn't meet your need, after configuring with the default configuration, you can customize it by doing:$ make menuconfigNow, in the menuconfig dialog, you can easily add or remove some features to/from AT91Bootstrap as the same way as kernel configuration.
Move to
<Exit> with arrows and press this button hitting the Enter key to exit from this screen.
Build AT91Bootstrap
Then you can build the AT91Bootstrap binary by doing:$ makeIf the building process is successful, the final .bin image is build/binaries/at91bootstrap.bin.
Build U-Boot from sources
Getting U-Boot sources
Dedicated page on U-Boot wiki: http://www.denx.de/wiki/U-Boot/SourceCode
You can easily download U-Boot source code from Linux4Microchip GitHub U-Boot repository:
- clone the Linux4microchip GitHub U-Boot repository
$ git clone https://github.com/linux4microchip/u-boot-mchp.git Cloning into 'u-boot-mchp'... remote: Enumerating objects: 951876, done. remote: Counting objects: 100% (17718/17718), done. remote: Compressing objects: 100% (5735/5735), done. remote: Total 951876 (delta 12391), reused 15314 (delta 11846), pack-reused 934158 Receiving objects: 100% (951876/951876), 164.77 MiB | 401.00 KiB/s, done. Resolving deltas: 100% (790362/790362), done. $ cd u-boot-mchp/
- The source code has been taken from the master branch which is pointing to the latest branch we use. If you want to use the other branch, you can list them and use one of them by doing:
$ git branch -r origin/HEAD -> origin/master origin/dev/tony/sama7g5ek_optee origin/master origin/sam9x60_curiosity_early origin/sam9x60_early origin/sam9x60_iar origin/sam9x7_early origin/sama5d27wlsom1ek_ear origin/sama7g5_early origin/u-boot-2012.10-at91 origin/u-boot-2013.07-at91 origin/u-boot-2014.07-at91 origin/u-boot-2015.01-at91 origin/u-boot-2016.01-at91 origin/u-boot-2016.03-at91 origin/u-boot-2017.03-at91 origin/u-boot-2018.07-at91 origin/u-boot-2019.04-at91 origin/u-boot-2020.01-at91 origin/u-boot-2021.04-at91 origin/u-boot-2022.01-at91 origin/u-boot-2023.07-mchp origin/u-boot-2024.07-mchp origin/uboot_5series_1.x $ git checkout origin/u-boot-2024.07-mchp -b u-boot-2024.07-mchp Branch 'u-boot-2024.07-mchp' set up to track remote branch 'u-boot-2024.07-mchp' from 'origin'. Switched to a new branch 'u-boot-2024.07-mchp'
Cross-compiling U-Boot
Before compiling the U-Boot, you need setup cross compile toolchain in the section. Latest versions of U-boot (2018.07 and newer) have a minimum requirement of 6.0 version of the GCC toolchain. We always recommend to use the latest versions.
Once the AT91 U-Boot sources available, cross-compile U-Boot is made in two steps: configuration and compiling. Check the Configuration chapter in U-Boot reference manual.
Go to the configs/ to find the exact target when invoking make.
The U-Boot environment variables can be stored in different media, above config files can specify where to store the U-Boot environment.
# To put environment variables in nand flash: sam9x60_curiosity_nandflash_defconfig # To put environment variables in SD/MMC card: sam9x60_curiosity_mmc_defconfigHere are the building steps for the SAM9X60-Curiosity board:
# You can change the config according to your needs. make sam9x60_curiosity_mmc_defconfig makeThe result of these operations is a fresh U-Boot binary called
u-boot.bin corresponding to the binary ELF file u-boot. -
u-boot.binis the file you should store on the board -
u-bootis the ELF format binary file you may use to debug U-Boot through a JTag link for instance.
Build Kernel from sources
Required packages
You must install essential host packages on your build host. These requirements are listed in the Linux kernel documentation with the chapter Install build requirements. You must follow this process which includes, but not limited to, the following packages:
- build-essential
- flex
- bison

Build Yocto/Poky rootfs from sources
Note that building an entire distribution is a long process. It also requires a big amount of free disk space. The support for Microchip AT91 SoC family is included in a particular Yocto Project layer:meta-atmel. The source for this layer are hosted on Linux4SAM GitHub account: https://github.com/linux4sam/meta-atmel
Building environment
A step-by-step comprehensive installation is explained in the Yocto Project Quick Build. The following lines have to be considered as an add-on that is AT91 specific or that can facilitate your setup.
Prerequisite
Here are the reference pages for setting up a Yocto Project building environment: What You Need and How You Get It.
add git-lfs to the package requirement list from whichever Linux distribution you use.
For instance, on Ubuntu or debian, these packages need to be installed on your development host:
sudo apt-get install gawk wget git-core git-lfs diffstat unzip texinfo gcc-multilib \
build-essential chrpath socat cpio python3 python3-pip python3-pexpect \
xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \
pylint3 xterm
Step by step build procedure
here is a copy of the README procedure available directly in the meta-atmel layer. This file in the meta-atmel layer repository must be considered as the reference and the following copy can be out-of-sync.
starting with Linux4SAM 2021.04 release, the meta-atmel layer supports Yocto Project templates, so make sure you create a new build environment using oe-init-build-env
This layer provides support for Microchip microprocessors (aka AT91)

Using SAM-BA to flash components to board
NAND Flash demo - Memory map
Install SAM-BA software in your PC
In addition to the official SAM-BA pages on http://www.microchip.com, we maintain information about SAM-BA in the SoftwareTools page.
use SAM-BA 3.8.y onwards. You can download it here: SAM-BA 3.8.1 release page.
Launch SAM-BA tools
- According to this section make sure that the chip can execute the SAM-BA Monitor.
QML language for scripting used for flashing the demos, most common SAM-BA action can be done using SAM-BA command line.
For browsing information on the SAM-BA command line usage, please see the Command Line Documentation that is available in the SAM-BA installation directory: doc/index.html or doc/cmdline.html .
SAM-BA includes command line interface that provides support for the most common actions:
- reading / writing to arbitrary memory addresses and/or peripherals
- uploading applets and using them to erase/read/write external memories
The command line interface is designed to be self-documenting.
The main commands can be listed using the "sam-ba --help" command:
SAM-BA Command Line Tool v3.8 Copyright 2024 Microchip Technology Usage: ./sam-ba [options] SAM-BA Command Line Tool Options: -v, --version Displays version information. -h, --help Displays this help. -t, --tracelevel <trace_level> Set trace level to <trace_level>. -L, --applet-buffer-limit <SIZE> Set applet buffer limit to <SIZE>
bytes (default 131072). -x, --execute <script.qml> Execute script <script.qml>. -p, --port <port[:options:...]> Communicate with device using <port>. -d, --device <device[:options:...]> Connected device is <device>. -b, --board <board[:options:...]> Connected board is <board>. -m, --monitor <command[:options:...]> Run monitor command <command>. -a, --applet <applet[:options:...]> Load and initialize applet <applet>. -c, --command <command[:args:...]> Run command <command>. -w, --working-directory <DIR> Set working directory to <DIR>.
Additional help can be obtained for most commands by supplying a "help" parameter that will display their usage.
For example "sam-ba --port help" will display:
Known ports: j-link, serial, secure
Command that take an argument with options (port, monitor, applet) will display even more documentation when called with "help" as option value.
For example "sam-ba --port serial:help" will display:
Syntax:
serial:[<port>]:[<baudrate>]
Examples:
serial serial port (will use first AT91 USB if found otherwise first serial port)
serial:COM80 serial port on COM80
serial:ttyUSB0:57600 serial port on /dev/ttyUSB0, baudrate 57600
Configure NAND ECC
Using default PMECC parameters
when choosing the board variant with the -b parameter of SAM-BA, the default PMECC configuration for the NAND populated on the board is valid. You can verify its value by running the command that reads one byte in a dummy file (named test.bin in the following command):
# sam-ba -p serial -b sam9x60-curiosity -a nandflash -c read:test.bin:0:1
Opening serial port 'ttyACM0'
Connection opened.
Detected memory size is 536870912 bytes.
Page size is 4096 bytes.
Buffer is 12288 bytes (3 pages) at address 0x003085a0.
NAND header value is 0xc2605007.
Supported erase block sizes: 256KB
Executing command 'read:test.bin:0:1'
Read 1 bytes at address 0x00000000 (100.00%)
Connection closed.
You can figure out that the default PMECC parameter for this sam9x60-curiosity board is 0xc2605007.
: Note that if you connect a serial console to the SoC RomCode default UART, you can see even more details about the NAND ECC parameters given by the SAM-BA Applet:
Applet 'NAND Flash' from SAM-BA Applets Framework 3.8 (v3.8). Initializing NAND ioSet1 Bus Width 8 PMECC configuration: 0xc2605007 Sector size: 512 Sectors per page: 8 Spare size: 256 ECC bits: 8 ECC offset: 152 ECC size: 104 PMECC enabled Buffer Address: 0x003085a0 Buffer Size: 12288 bytes NAND applet initialized successfully.If you want to change the default PMECC parameters you can simply specify another value on the SAM-BA command line with the
-a nandflash argument as shown below:
# sam-ba -p serial -b sam9x60-curiosity -a nandflash:help
Syntax: nandflash:[<ioset>]:[<bus_width>]:[<header>]
Parameters:
ioset I/O set
bus_width NAND bus width (8/16)
header NAND header value
Examples:
nandflash use default board settings
nandflash:2:8:0xc0098da5 use fully custom settings (IOSET2, 8-bit bus, header is 0xc0098da5)
nandflash:::0xc0098da5 use default board settings but force header to 0xc0098da5
For information on NAND header values, please refer to SAMA5D4 datasheet section "12.4.4 Detailed Memory Boot Procedures".
By reading this in-line documentation we can specify the NAND PMECC parameter with this command:
# sam-ba -p serial -b sam9x60-curiosity -a nandflash:::0xc2605007 Opening serial port 'ttyACM0' Connection opened. Detected memory size is 536870912 bytes. Page size is 4096 bytes. Buffer is 20480 bytes (5 pages) at address 0x0020a240. NAND header value is 0xc2605007. Supported erase block sizes: 256KB Connection closed.
